Paper Title:
Finite Element Microcosmic Contact Analysis of True Rough Surfaces Based on ANSYS
  Abstract

According to the significance of the contact between mechanical surfaces and the deficiency of the study at present, the finite element analysis software—ANSYS and APDL tool are used to set up a microcosmic contact model due to the micron scale surface topography data of the parts measured by the laser measurement equipment named OLYMPUS, and simulate the complete contact process of rough surfaces based on the theory of elastic-plastic transmutation. A solving algorithm of gird meshing based on multi load steps for the problems of grid precision and grid distortion is presented during microcosmic contact process. Through the disposal module /POST1, the relations between the real contact area, the load and stress are given, which offers the foundation for the analysis of contact mechanism and connect capability between mechanical joint surfaces.
